Background & Objectives: Urinary tract infections (UTI) are among the most common bacterial infections in humans. One of the most frequent form of UTI is asymptomatic bacteriuria. The aim of this study is to determine the prevalence of asymptomatic bacteriuria in female students of Babol Islamic Azad University.

  Methods: This research was carried out on 207 female students from Babol Islamic Azad University in 2002. The age ranges of the students were between 18-29 years. Mid-stream urine (MSU) was collected from students. Urinalysis and bacteriological identification culture of MSU were done twice on all specimens. The prevalence of asymptomatic bacteriuria was determined by dividing the total number of observed bacteriuria by the total number of samples.

  Results: Bacteriological tests of MSU revealed that 19 (9.2%) cases were positive for asymptomatic bacteriuria. The microbe most frequently causing asymptomatic bacteriuria was staphylococcus saprophyticus in 7 (36.8%) cases Escherichia coli in 6 (31.6%) cases and Klebsiella in 3 (15.8%) cases.

  Conclusion: Asymptomatic bacteriuria was highly prevalent in our study. Therefore, young women must consider general health rules about genitourinary system to avoid asymptomatic bacteriuria.
